Possible memory leak for development mode standalone (Setting UI.Text.text)



1. What happened
Attached project indicates Profiler.GetTotalAllocatedMemoryLong() value growth for players build in Dev mode. This wasn't so in 5.6.1p1. In release mode the behaviour wasn't noticed as well.

Observing this behaviour for Win and OSX standalones and for UWP (was launching this one from VS2015 in Debug mode).

2. How we can reproduce it using the example you attached
- Build standalone player with Dev mode checked
- Run it
- Observe 'Total allocated' value growing.

It later starts jumping up and down, but the trend seems to grow beyond previous 'max'.

    So far, the only "solution" I found to this issue is to close the profiler window. Monitoring the UI resources was actually causing the memory leak. That fixed the problem for me.

    Very unfortunate that this is marked as fixed.

    Still present in "2017.1.1f1".

    Happening to me as well on 2017.1.0f3. The editor playmode keeps growing the memory usage and crash my system.

    Also, the problem doesn't happen in the build.

    I can confirm that this is happening in 2017.1.0f3. Shared UI Mesh keeps allocating memory rapidly in play mode until the Unity Editor crashes.

    I can confirm that this is still happening in 2017.1.0f3. It's only happening in the editor - not in the build. Mesh memory goes up constantly while in play mode. After exiting play mode, the memory doesn't get freed up resulting in an eventual crash of the editor.

    Claimed to be fixed in 2017.1.0p2 release notes, but still reproducible in the editor. My repro project still leaks ~20 megs per second.

    this is still happening in Unity 2017.2.0b4 (64-bit), in both android , win standalone and editor playback. I added a new bug report but was marked as duplicate, even though this duplicate says fixed.
